Multi-Material Printing on a Single Extrusion 3D Printer

[@GabrielCastro_FL]

That is great!!! Do you have a tutorial on how you design something like that?

[@MrErdreich]

Thanks! Not exactly, but I do have this video that shows how to import SVGs and manipulate them in Tinkercad: kzbin.info/www/bejne/lYbWpJ-Yh9maf5I Let me know if this helps and I'd be happy to put more resources together!

Hey! I used a flexible filament in my Dremel 3D45 and then paused the print and changed the filament to a PLA and manually edited the settings on the printer and now my printer is mad and no filament is coming out even when I’m hitting purge.. any idea on how to fix? Also, if I do the settings correctly next time, have you done a print where you toggle between flex and PLA In one print successfully? Thx!

[@MrErdreich]

Happy to help! What type of nozzle are you using (copper, brass, steel, etc)? TPU really needs a harder nozzle like a coated copper or hardened steel one. I would assume you're using a brass, nickel, or copper nozzle and the TPU has just completely jammed the inside of it. If you plan to swap between different filaments, I would suggest a coated hardened steel nozzle and that you increase your overall print temp to 225 c rather than the default 205 or so typically used for PLA.

Greetings, Great Instruction !!!!!,,,, I'm new to the 3D Printing scene, and have ideas to create some prints that serve a Utility function, and would like your advice on how to go about printing out something that is mostly hard , though has three sides that will clip onto a rail , so those edges would maybe be TPU , a filament that gives or clicks into place when pushed together.... Gluing would not be an option, as I would not trust it in the long run..... Any information in printer models and Ext heads would help.... Thanks.....

Thanks for the view and happy to assist! TPU comes in many different forms, some harder and more rigid than others which makes it easier to print, especially when combined with other rigid materials. I would suggest looking into GizmoDorks TPU, I find it to be the best compromise of rigid and flex and easy to print personally. You might also get away with a rigid material that has some flex to it, like PETg. PETg and TPU also print at similar temperatures, so swapping between those materials mid print would be easier to do than say PLA and TPU. Hope this helps!

@@MrErdreich Yes, Thanks for the information on the Filament, I now have to make a decision on a Printer.....

[@MrErdreich]

There are many great options out there, but not many of them are suitable to print TPU and flexible materials out of the box. Heated glass beds, direct drive extruders, and 2.85 mm filament printers typically do better with this if you were planning or primarily printing flexible or abrasive materials over PLA.

why would you use pause at to change filament over the change filament script?

[@MrErdreich]

One in the same I suppose, I've always done it this way personally, maybe because I often changed to different filaments (PLA to TPU for example) and wanted a bit more control, but the change filament script would work as well.

@@MrErdreich I have a Dremel 3D Single nozzle printer. I’ve been asked by students to do this but I didn’t know it was possible until now. What would I look for in my slicing software to determine if it’s possible with my equipment?

[@MrErdreich]

@@AlFitch To my knowledge, Dremel uses a Cura-based slicer just like Lulzbot so you should be able to find the same menu I used in this video, though it might be in a slightly different place. Alternatively, you could use the full-fledge Cura by Ultimaker and add your Dremel to that using an existing profile. This will give you more settings and more control. You could even use Lulzbot Edition just like I showed in this video as well because all of these different programs are based on the same core Cura program.

This is great!
